why is keystone using these tires if people are having these problems? i thought my raptor was an exception to some of the problems since i really haven't had anything for the first year till now. here we go!!!

We're approaching 6,000 miles on our original Towmax tires with no problems - yet. Only one flat so far from a small piece of steel. I try to closely monitor tire pressure so perhaps I'm the lucky one so far.

Think about your situation and do some troubleshooting. Most likely your OE tires would live a normal life expectancy on 6000# axles.
Toy haulers are inherently loaded to the max. ST tires degrade about 1-2% a year depending on the sit around time or any mistreatment such as overloading or under inflation.
Your OE tires with an anomaly of 2% below maximum operating pressure on all tires puts their total load capacity below your minimum required axle capacity. It’s a situation seen time and time again with Keystone trailers. Such OE tires are going to fail. Some sooner than others.
Because of the dynamics of the RV trailer the ST tires NEED at least 12% load capacity reserves above GAWR. More would be better but 12% will do for axles that are weighed often and the loads are kept evenly balanced.
